Question

She was expecting 122.7 grams of lead for her lesson that day but only got out 107.9 grams of lead. What was the percent yield of her reaction

Answer 1

The equation for percent yield is

`PercentYield= (Actual)/(Theoretical) X 100`

As such, the theoretical yield or expected yield is, in this case, 122.7g of Pb, the actual in this case is 107.9g so we have

`PercentYield= (107.9)/(122.7) X 100 \\ Percent Yield=0.879381X100 \\`

Therefore, the percent yield of her reaction is 89.94%
